As a client of Codex, I would like to have access to its APIs and functionalities as part of a library instead of having to spin it in a different process manually.

This also aligns with the new goals of the IFT of having all the subprojects available as libraries that can be used by anyone.

The end goal is that as part of another app, we can start and use Codex features by calling them directly from our code instead of relying on a REST API. This can be done using C Bindings.
